Patented March 30, 1909.

Application filed October 9, 1906. Serial No. 338,176.

To all whom'it may concern:

Be it known that I, CLARENCE C. TRAVIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Shaping and Dipping Light-Mantles, of which the following is a full, clear and exact specification.

This invention relates to improvements in machines for shaping and dipping light mantles, and it has for its primary object to provide improved means for conveying the mantles to the shaping flame and for dipping the mantles in a preserving solution after they have been shaped.

A further object is to provide an im proved machine of this character, which will be simple and cheap in construction and effective in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating an exemplification of the invention, and in which,-

Referring more particularly to the drawings, the same reference numerals designate similar parts throughout the several views.

In this exemplification of the invention the machine comprises front and rear standards 80, 81 suitably spaced from each other, and connected to form a supporting frame by means of cross bars 32, located preferably at the top thereof, and longitudinal bars 33 near the bottom. Between the standards, preferably near the upper ends thereof, are axles 3a, suitably journaled or mounted therein. Secured to, or formed on the ends of these axles, preferably adjacent the inner face of each of the standards, is a carrying or lifting reel, designated generally by the numeral 35, which are provided with arms 36, and which are of considerable length, and pivoted to the free end of each arm is a member or hook 37, each of which is provided with a shouldered portion 38 to form a seat, preferably adjacent the free end there of, and an inclined face or extremity 39, for a purpose to be set forth. A sprocket wheel &0 is secured to the inner face of each of the reels 35, by any suitable fastening means such as screws or bolts 41 passing through slots 42 in the sprocket wheels, and by means of which the sprockets may be rotatively adjusted with relation to the reels 35.

A bar or support l3 extends across the frame work adjacent each pair of standards and is secured by its ends to the standards, as at 44. Each of these bars or supports is parallel with its adjacent axle 3st and is located below said axle. Projecting from said bar or support are suitable arms or brackets 45, which are preferably located within the frame, and journaled in these arms or brackets are axles 4:6, which are parallel with and located preferably beyond the axles 34. Secured to these axles 46, and adjacent the standards, are sprocket wheels 17, each of which is in direct alinement with the adj acent sprocket 40. Suitable endless sprocket or conveyer chains 48 are arranged to run lengthwise of the frame and pass around the respective sprockets a0. a7, thereby causing the axles 3% and reels to revolve in unison, as will be set forth.

Extending lengthwise of the frame, adjacent to, and adapted to receive and support the upper runs of the chains or conveyer-s etS are trough or channel-shaped members l9, (more clearly shown in Fig. 13). These members preferably terminate short of the standards andare supported or secured in position by means of brackets or braces 50, one end of which are secured to the respective standard while the other ends engage and are secured to said members 19 adjacent the extremities thereof. Suitable tracks or supports 51 are also secured lengthwise of the frame adjacent and in close proximity to the lower runs of the conveyers or chains a8 and are preferably L shaped and arranged chains or conveyers e8 are projections or pins 51, which serve as holders for the mantle support 55 and which comprise rods or bars provided with spaced circumferential grooves 55. The mantles are lGlHOVfiblY secured to and depend from these bars or rods. When these mantle supporting rods or bars 55 are resting upon the upper runs of the chains or conveyers 4&8, they are prevented from displacement by means of suitable guide boards or shields 56, which are secured to and supported by the trough-shaped members 4.9, and project slightly above the members; the front ends thereof being bent or deflected as at 57 to permit the entrance of the rods or bars and to serve as a means for positioning the rods on the conveyer.

lVhen the rods are transferred from the upper to the lower runs the rods will rest upon the tracks or supports 51 and will be advanced by means of the projections or pins 54, the upright portions of the tracks or supports serving to prevent the displacement of the rods. The rear extremities of these tracks or supports 51 extend for some distance beyond the sprockets 17 and are bent or deflected upwardly as shown at 58, and secured adjacent the forward extremities thereof in any suitable manner is a member or guide which also bent or inclined upwardly. If desired, these inclined ends may both be integral with the tracks or supports 51, or separate therefrom.

As the conveyer advances the front reels will rotate so that the pivoted members 37 supported by the arms 86 thereof will be successively brought adjacent one of the mantle supporting rods or bars 55, so that the seats 38 will engage and raise one of the bars from the upper runs of the conveyer chains 48 and eventually place the same upon the lower supports or tracks 51, while the rear carrier or lifting reels will raise the rods or supports 55 from the lower tracks or supports and place the same upon the upper runs, as will be described.

The conveyer is intermittently advanced in any desired manner, but a simple and effi cient means for accomplishing this movement comprises a drum 60 rotatably supported by one of the standards 61 constituting a portion of the frame and located preferably intermediate the front and rear standards 30, 81, substantially midway of length of the frame. Projecting from this drum is a yoke 62, to which is pivotally connected one end 63 of a bar or rod Get, the forward or free end of which is preferably beveled or inclined as at 65, and terminates at the extremity in a shoulder 66, which is adapted to engage laterally projecting pins or lugs 67 on the face of one of the sprocket wheels 47 (see Fig. 23). This bar or rod may be made in sections which telescope with each other and held in their adjusted positions by means of a suitable sleeve or collar 68.

As the drum is rotated in a forward direction the shoulder 66 will push upon the engaging pin or lug 67 and rotate the sprocket 47 one step, which will also advance the conveyor 48 one step. In order to prevent the next advancing pin 67 from engaging the rod or bar 64 and disengaging the shoulder 66 from the pin before the drum has completed its forward movement, the end of the rod or bar is provided with a notch or recess 69, into which the advancing pin enters. When the drum is reversed the inclined face will be drawn across the pin which will raise the shouldered ex tremity sufiicient to permit it to drop into operative position with relation to the next pin; the extremity 70 of the rod or bar serving to prevent the end of the rod or bar from dropping out of position.

The drum is preferably provided with two spaced peripheral grooves 71, 72, which communicate with each other by a transverse groove 73. A rope or cable 74 is seated within these grooves and crosses from one groove to the other through the transverse groove 73, and is secured to the drum by means of a clip 75, preferably extending across the transverse groove 73 and removably held in position by suitable screws or bolts 76.

The extremities of the rope or cable are crossed and one is secured to a vertically movable piston 77 adjacent the upper extremity thereof and above the drum, and the other end is adjustably secured to the piston below the drum in any desired manner, such as by a suitable sleeve or collar 7 8, so that when the piston is raised it will rotate the drum in a forward direction, and when lowered will rotate it in the opposite direction. This rod or piston 77 may be raised and lowered in any suitable manner. but preferably by means of a piston head (not shown) which moves in a cylinder 79 supported by the frame of the machine and which is adapted to receive a suitable fluid, such as air, for moving the piston. Air is supplied to the cylinder from any suitable source of supply through a pipe or tube 80, which communicates with a valve casing 81, andleading from said casing is a pipe 82 which communicates with the top of the cylinder on one side of the piston, and a pipe 83 which communicates with the bottom of the cylinder on the opposite side of the piston. The valve casing is also provided with exhaust ports 84, 85, to which are attached tubular members 86, each of which is preferably provided with an opening or aperture 87 through the side thereof. Seated in these tubular members 86 is a plug or screw 88 having a head 89, by means of which they may be adjusted to regulate the openings 87. A suitable jam nut 90 is also provided on each of the screws or plugs 88, by means of which the latter may be held in their adjusted position. A valve plug 91 is arranged within the casing, and is preferably provided with ports or passages 92, 93, 94. 'l hese-parts are so arranged that when the plug 91 is in its normal position, as shown in Fig. 97, the port 92 will be in communication with the supply pipes 80 and 82, the port .93 will be out of operative position, and the port 9-ftwill be in communieation with the pipe 83 and exhaust port 85. Assuming the piston 77 to be in its lowest position as shown in Fig. 6, and the valve is rotated so that the port 92 will form a communicating passage from the pipe 80 to the pipe 83, the air will pass to the bottom of the cylinder and raise the piston. In this position the port 93 will form a communication between the pipe 82 leading from the top of the cylinder and the exhaust port 84, thereby permitting the air above the piston to escape. W hen the valve is reversed or assumes its normal posi tion to direct the air to the top of the cylinder. the air below the piston will escape through the port or passage 9st and exhaust port 8?, thus permitting the piston to ascend. It will be seen that with this construction the rapidity of the movement of the piston may be governed by. the size of the exhaust openings 87, which are themselves regulated by the adjustment of the screw or plug 88. If desired, suitable cocks or plugs 95 may be provided in the pipes 82, 83, to permit the escape of any surplus lubricating oil which may have been inserted in the cylinder in any desired manner or forced therein through these plugs or cocks. This valve is preferably operated by means of an operating handle 96 located at the front of the machine. which slides in a suitable guide 97 (see Fig. 27) on one of the front standards 30. The lower end of this handle connected to one arm of a bell crank or rock lever 98, jin'eferably located adjacent the base of the machine; and extending from the other arm of the lever 98 is a connecting rod or bar 99, which is preferably located beneath and protected by the longitudinal bar 33. The free end of this bar 99 is connected to one arm of a bell crank lever 100, which is pivoted to the inside of the standard or support 61. The other arm 101 thereof is located on the outside of the standard 61, and connected thereto is one end of a vertically sliding bar or rod 102, the upper end of which moves through a suitable guide 103 on the standard 61 and which is located preferably above the valve 81.

Secured to the bar or rod 102 at a suitable point is an arm 101, and a link 105 connects the free end of this arm with the valve plug 91 so that when the bar or rod 102 is moved up and down the link 1'05 will serve to rotate the plug 91, as will be understood. A spring 100 is secured by one end to the arm 10 1- and to the standard 61 by its other end and serves to keep the bar or rod 102 raised to hold the valve plug 91. in its normal position as shown in Fig. 27*. A suitable locking means is provided for fastening or holding the bar or rod 102 down against the tension of the spring 106, which comprises a dog or pawl 107 pivotally connected by one end to the guide 103. The free end stands adjacent the upper end of the rod or bar 102, and is provided with a lip or shoulder 108, which normally rests against the face of the rod or bar 102, and is held in position by means of a suitable spring 109. When the extremity of the rod or bar 102 moves below the lip or shoulder 108 on the dog or pawl, the spring 109 will rock the latter on its pivot and cause the lip or shoulder to stand in the path of the upward. movement of the end of the arm or bar and thereby loclrthe same in its lowest position and hold the valve open. The lock thus formed is automatically released by means of an arm or member 110, one end of which is pivotally connected to the standard 61, as at 111, and the free end 112 stands between the rod or bar 102 and the dog or pawl 107 and is normally held down out of engagement with the dog or pawl by means of a spring 113.

A pin or lug 114: projects from the piston rot. '77, and when said rod has about reached the limit of its upward movement, this pin or lug will engage the arm or member 110 and raise the free end thereof against the tension of the spring 113. As this member is raised it engages the dog or pawl 107 and. rocks the same backward against the tension of the lip or shoulder 108 out of engagement of the end of the rod or bar 102. \Then thus released the spring 106 will move the rod or bar 102 upward and thereby rotate the valve plug 91 to the position shown in Fig. which will direct the air into the top of the cylinder and the piston will innnediately begin to descend. As the piston rod 77 descends, the springs 113, 109 will return the members 110, 107 to their normal positions. Thus it will be seen that on each forward or upward movement of the piston the conveyer will be advanced one step, and will remain still as the piston is returning. As the conveyer advances the mantle carriers or supports which are placed upon the upper runs of the conveyer chains, adjacent the ends 57 of the guide boards 56, are fed toward the front end of the machine, and as they approach the front end their extremities are engaged by suitable deflectors or positioning members 115 (see Figs. 2 and 3), which properly positions them on the conveyer. The carrier or lifting reels will rotate with each step of ad 'ance'ment of the conveyer so that one of the arms 30 thereof will be in such a position that the pivoted members 37 thereon will cause the seat 38 to engage and raise the foremost one of the mantle supports from the upper run of the belt and carry it forward beyond the front end thereof in a position to be removed from the carrier and placed over the shaping flame, after which it is replaced in a manner to be set forth, and carried into engagement with the guide 59 of the tracks or supports and into engagement with the lower run of the conveyer chains and is intermittently moved along the lower track or support 51 toward the rear of the machine. If for any reason the mantle support should fall from the carrier or be placed improperly upon the guides 59 it will be straightened and moved backward so as to be engaged by the projection of on the lower run by means of suitable projecting arms, pins or lugs 116, on the.

front axle 40 adjacent the sprockets 47 thereon.

The mantles are formed and secured to the supporting rods or bars 55 before being placed upon the conveyer, and before they are finally shaped by a Bunsen flame, as will be described, it is necessary to remove the cotton from the fabric. This is preferably accomplished by burning the same with a strong flame which necessitates removing the support and mantles from the conveyer and replacing them upon the conveyer after having been burned. A simple and efiicient means for automatically accomplishing this end will now be described.

Secured to the standards 30 above the upper runs of the conveyer and projecting toward the rear of the frame arearms or projections 117, which may also be supported by members 118 extending from the braces or brackets Extending above the arms or projections 117 preferably adjacent the standards, are cars 119, and extending across the framework and journaled in these ears is a rock shaft 120, which may be prevented from displacement in any suitable manner. The end of this shaft on the side of the frame adjacent the drum is preferably be'nt downward to form an arm 121. A pair of arms 122 are secured by one end to the shaft 120 within the frame and are held in any desired position by a suitable screw or bolt 123. These arms may be made in sections if desired and are of a length to project forward for some distance above and acent the upper runs of the conveyer chains, and pivotally connected to the for ward end of each arm is a depending link 124. The body of the link is preferably offset as at 125, with the end bent inward as at 126, the extremity of which is bent upward as at 127, preferably parallel with the offset portion 125. This extremity 127 is notched or bifurcated as at 128, and is adapted to reeeive and hold one of the mantle supporting rods Secured to the arms or projections 117, adjacent the links 12 1, are brackets 129, to which are secured spaced guides 130, and these guides are so located that the offset portions 125 of the links 121 will engage and move against said guides, and the links are prevented from displacement by means of a lateral projecting pin or lug 131 moving between the guides 130. The links 121 and the in'ardly bent portions 126 are of such a length that when in a normal position the portion 127 will stand adjacent the outside of and project slightly above the channel or trough-shaped chain guide 4:9.

Projecting rearwardly from the shaft 120 is an arm 132, and adjustably secured thereto is a counterbalancing weight 13? for the arms 122 and links 124. These brackets 129 preferably project for some distance above the arms or projections 11? to prevent lateral displacement of the links 124 and also to allow the mantle supporting rod 55 resting in the notch 128 to be raised high enough so that the entire area of the mantles supported thereby may be brought between and exposed to the flame from a series of oppositely disposed jets or burners 134i proj ecting from the spaced parallel supply pipes 135. These pipes are arranged between and supported by the arms or projections 11? preferably adjacent the free ends thereof; the tips or burners 13 being preferably inclined or deflected downward and toward each other. These pipes 135 are connected to a mixing valve, designated generally by the immera-l 136. the construction of which will form the subject-matter of a separate a 'iplication. This valve receives an air sup ply through a branch pipe 137, leading preferably from the air pipe 80 which supplies the cylinder 79, and a gas supply from any suitable source, through the pipe 138, and each of these supply pipes may be provided with regulating valves 139, located preferably adjacent the mixing valve 136. This mixing valve is provided with a plug, to which is secured in any desired manner an operating handle or lever 140, provided with apertures 1 11 adjacent its free end. A link 142 is connected by one end to the end of the arm 121, and said link is provided with a slot 143 adjacent its free end, and is loosely connected to the operating handle or lever 1410 by means of a screw or bolt 114:

passing through the slot lei-3 into one of the apertures 141. Passing through the slot 11 is a bolt or member 1 15, which is adjustable in said slot and is held in position by means of a nut 141-6, and may be adjusted toward or away from the screw or bolt 144: so that the link 142 may have an independent movement with relation to the operating lever or handle 140, the end of the slot- 143 and the bolt or member 1415 forming tappets adapted to engage the bolt or screw 14 1, thereby rendering it possible to regulate the operation of the mixing valve. Thus when the arm 121 is moved to operate the arms 122 to raise the mantle support 55 between the burners 134:, the member 145 will engage the screw or bolt 14% to move the handle or lever 1.40 to raise the flame of the burners, and when the arm 121 is moved in the opposite direction to lower the mantles, the end of the slot will engage the screw or belt 144 and move the lever or handle in the opposite direction to lower the flame. This arm 121 is preferably moved by the drum (30, to the shaft of which is loosely pivoted a bell-crank lever, having depending arms 11?, 148. The arm MS may be made in sections and adjustable if desired, while the arm 1417 is preferably longer, and is provided with. a plurality of a ertnres in its free end. A connecting bar or link 111) is also provided with a plurality of apertures in one end, any one of which is adapted to register with any of the apertures in the arm 1-1-0, by means of which it is adjustably secured to said arm, the other end being pivotally connected to the arm 121 of the shaft 120.

Secured to the face of the drum 60 is a stationary pin or lug 150 and an adjustable lug 151. These lugs are so arranged that as the drum (i0 is about to complete its forward movement the lug 151 will engage and move the arm 117, thereby drawing on the connecting rod or link 119 to rock the shaft 120 for raising the mantle support which rests in the links 121. The parts will be retained in this position by the weight 133 until the drum (30 is about to complete its rearward movement, when the pin or lug 150 will engage the other arm 118 for rocking the shaft in the opposite direction. By adjusting the lug or stop 1.51 the length of movement of the arm 14:7, and the height to which the mantle support is raised, may be regulated. After the mantles have been thus subjected to the flame, the cotton will be burned out of the mantles and the support will then be deposited upon the upper runs of the conveyer chains by means of the notched ends of the links passing far enough below the chain guide or support 419 to disengage the ends of the bars or supports 55. The conveyer will then be intermittently advanced and the support with the prepared mantle will be raised by the pivoted members 37 on one of the arms 36 of each of the carrying reels 35 until it has reached the extreme forward position as shown in Figs. 1 and 2. In this position it is ready to be lifted from the carrying reel and placed over the shaping flame in any desired manner. A simple and effective mechanism for this purpose comprises a pair of parallel vertically movable bars 152, which move in guides 153 suitably located on the frame. Journaled across the base of the frame adjacent the bars 152 is an axle 1, projecting from each end of which is a forwardly eX- tending arm 155. Disposed between the lower end of each of the bars 152 and its respective arm 155 is a link connection, com prising members 156 and 157, which are spaced from each other by means of the bolts or rivets 158. The end of the rod 152 is secured between the ends of the members by means of atransverse pin or bolt 159, and the arm 155 is secured between the lower e:; tremities by means of a similar pin 169. The members 156 are provided with slots 161 for the reception of the end of the pins 159, 160 so as to permit the ends of the rods 152 or the arms 155 to move independently to accommodate any uneven or rocking movement to prevent injury to the bars 152. This lifting mechanism is counterbalanced by means of an adjustable spring 162 surrounding one end of the shaft 15%, one end of which 162 engages the frame and the other a collar 162 on the shaft. An operating handle 163 sliding in suitable guides 16% is connected to one of the bars 152 as at 165 and by moving this handle up and down the bars 152 will be simultaneously raised or lowered.

Adjustably secured to each of the rods 152 is a collar 165, which is preferably provided with a flat face 166, and a bracket 167 is adj ustably secured by one end to said face by means of suitable screws or bolts 168 passing through slots 169 and into the collar 165. The forward ends of these brackets are notched to form seats 170 for the mantle support 55.

Pivoted to the face of the bracket 167, preferably adjacent its forward end and in proximity to the seat 17 0, is a weighted latch 171, which is adapted to engage a lateral projection or stop 172; and projecting from the latch at a point adjacent the free extremity of the bracket and beyond the seat 170, is a laterally extending pin or lug 173. These brackets are arranged in alinement with each other, and are adapted to be simultaneously raised so that the pin or projection 173 will engage the inclined face 39 of the pivoted members 37, which stand within the path of their upward movement. The brackets being so located as to pass on the inside of the members 37. hese members 37, together with the mantle support 55, being heavier than the latches 171, will cause the latter to be moved about their pivots as the pin or projection 173 moves along the inclined face 39. This movement will continue until the brackets have been raised high enough so that the seats 170 will engage the mantle support held in the seats on the members 37, (as shown in Fig. 21). A slightly further upward movement will raise the mantle support off of the seats 38. The latches 171 being then heavier than the members 37, will move about their pivots and throw the members 37 backward, which will permit the brackets to be lowered with the mantle support and the mantles thereon. Arranged within the path of the clownward movement of the mantles are a series of shaping burners 17%, which pass inside of the mantles, to fill the mantles out and shape them by means of a strong Bunsen flame. The members 37 being relieved of the weight of the support and the mantles thereon, will swing slightly forward by gravity, so that the inclined faces 39 thereon will move out of the path of the upward movement of the pin or projection 173, so that when the brackets are raised after the mantles have been shaped, the extremities of the members 37 will pass in front of the pin or projection and the inclined face 39 will engage the mantle support 55, which will move it back far enough to cause the seat 38 to engage the support, the pin or projection 173 in this instance serving to prevent the members 37 from swinging too far outward. After the mantle support has been replaced upon the carrier reel the conveyer may be advanced another step. This operation is employed when depending mantles are to be shaped, but if the mantles were inverted the same operation would be employed, except the irackets would be raised toward a series of depending burners 175 located at the top of the machine, and in replacing the support on the carrier or lifting reels the bracket would have to be lowered below the members 37 and then raised, as will be understood, suitable stops 152 being provided on the rods 152 for limiting its movement. The members 37 will pass slightly below the lower track or guide 51, so that the ends of the supports 55 will engage and rest thereon, and also be disengaged from the seats 38 and moved forward by the lower run of the carrier away from the members 37 to permit the latter to move upward.

The shaping burners 174 comprise a series of burners communicating with a chamber 176, which is supplied wit-h gas through the pipe 138, which also supplies the burners 13 1, and a regulating valve 177 may be provided in the pipe adjacent the burners 17 1. Extending from the pipe is a tube 178, provided with a burner 179 for a pilot light by means of which the burners 17 1 and 175 may be lighted when needed. A branch pipe 180 also leads from the pipe 138 to the chamber 181 for supplying the burners 175, and a valve 182 may be provided for cutting oil the supply to the chamber 181 when not needed; and a suitable valve 183 may also be provided for cutting otl' the supply to the chamber 17 6 when the burners 17 4 are not to be used. The chamber 176 is also supplied with air from the pipe 80, which is provided with a suitable regulating valve 18%. A branch pipe 185 leads from the pipe 80, and also communicates with the chamber 181 for supplying air thereto, and said supply may be cut ofi' from the chamber by means of a suitable valve 186 in the branch 185. A similar valve 187 may also be provided in the pipe 80 adjacent the chamber 176 to cut oil the supply of air thereto when the burners 17 1 are not to be used. hen the mantles are lowered onto the burners 17 4 the gas and air are turned on and regulated by the valves 177, 184 and the burners lighted by the pilot light 179. During the process of shaping the mantles may be raised and lowered by operating the handle 168 oi the lifting mechanism. After the mantles have been thus shaped and the support 55 placed upon the track 551, they will be intermittently moved toward the rear of the machine until they reach the dipping tank 188, which is preferably removably supported upon tracks or guides 189 secured to the stand ards 61 and in such a position that. the tank will be located below the lower run of the conveyer chain 4-8 and extend across the frame. \Vhen in this position the support 55 will be lowered so as to dip the mantles in a suitable preserving solution in the tank, after which it is returned to the conveyor and advanced to bring the next support into position for a similar operation. A simple and efficient means for accomplishing this end will now be described.

Slidably mounted in suitable guides on each of the standards 61 is a vertical rod or bar 190, to the upper end of which is adjustably secured a sleeve or collar 191, and projecting from this collar is an arm or bar 192. which is located beneath and parallel with the lower run of the chain 48. A sleeve or, collar 193 is secured to the arm or bar 192 for longitudinal adjustment thereon, and a bracket 19% is secured to and vertically adjustable with relation to the sleeve or collar 193, by means of suitable screws or bolts 195 passing through slots 196 in the bracket and into the sleeve or collar 193. The upper edge of each of these brackets is corrugated or provided with depressions 197, adapted to receive and hold the supports 55 for dipping the mantles. These brackets normally stand in close proximity to the lower runs oi the conveyers and the tracks 51, and as the supports are advanced along the tracks 51 they will drop through an opening 198 (see Fig. 11) in the tracks and tall into one of the seats or depressions 197 in the brackets 19 1, as shown in Figs. 2, let, 15 and 17. These rods 190 are connected for simultaneous movement preferably by means of spaced members 199. forming links similar to the members 156, 157, which are secured by one end to the lower ends of the rods 190 and by their other ends to one end of arms 200, which are adjustably secured to an axle 201 adjacent the standards (3.1. This axle is supported by suitable journals 202, and is provided with a weight 203 which is heavy enough to normally raise the bars 1.90 to hold the brackets 194- in close proximity to the conveyer chains 4:8. Thus it will be seen that when the rods 190 are depressed the weight 20 will be raised, and when the rods are released the weight will return them to their normal position. In order to permit a st auly and uniform movement to the rods or bars 190 and prevent the supports 55 from being 'arred oil of the brackets 191, a suitable dash-pot 204 may be provided, the iston 205 o't which is connected to one of the rods or bars 190 by passing through a bli'lClCQll 20G thereon and held from displacen'ientby nuts 20? on each side of the bracket. lit desired, a suitable adjustable stop 208 may be provided on the rod 190 to limit its downward movement, and an adjustable stop 209 may be secured to the collar 191. and is arranged to engage the lower face of the tracks or supports 51 to limit the upward movement.

One of the arms 200 is provided with a slotted guide 210, preferably in the form of a bracket secured thereto, and passing through and extending below this guide is one end of a sliding bar or member 211, the upper end of which is provided with a slot 212. This bar or member may be supported in any desired manner, preferably by means of a bar or rod 213 secured thereto by one end preferably midway ot' the ends oi the member, the other end passes loosely through a suitable bracket 21-t secured to the standard 61, and said rod is prevented from disengagement from the bracket. by means of a suitable head or nut 215.

The lower extremity of the bar or member 211 is provided with a shoulder 216, adapted to engage one edge of the slotted guide 210, when raised into proximity thereto, and said shoulder is forced and held in engagement therewith by means of a spring 217 arranged on the opposite side ot the slotted guide. The late ally projecting pin or lug 11-1 on the piston rod 77 projects through suitable guides 218 secured to the standard 61, and projects beyond said guides and into the slot 212 of the bar or member 211. The extremity of this-lug or pin 114:

is provided with a circumferential groove or depression 219, which is adapted to receive and form guides or ways for the sides of the slot 212 of the members 211, and to prevent disengagement of the pin and bar or member. The extremity of this pin 11% is placed in the slot 212 by removing the member 220, which forms a closure for the top thereof. A weight 221 is secured to this bar or member 211, preferably above the slotted guide 210 on the arm 200, and serves to hold said bar or member 210 in its lowest position. Secured also to the arm 200 adjacent the slotted guide 210 is a bracket 222, and adjustably secured to the bracket is a laterally projecting lug or member 223, which is normally spaced from the bar or member 211.

As the piston-rod 77 rises the pin 11% will move in the slot 212 of the bar or member 211, until it strikes the top 220 thereof, which it will do as it is just about to reach the limit of its upward movement to move through the slotted guide 210 until the spring 217 engages the edge of the slot, which will force the shoulder 216 over the opposite edge of the slot. Vhen the piston rod descends the weight of the bar or member 211 will be transferred to the arm 200, owing to the fact that these two members will be locked together, and as the clashpot 20% will retard their descent, the piston will return more rapidly than these members. The extra weight being thus placed upon the arm 200 will overcome the weight 203 and cause the bars or rods 190 to de scend. This movementwill continue until the mantles held by the descending support enter the dipping tank 188, at which time the projection 223 on the bracket 222 will engage the bar or member 211, and move its extremity against the tension of the spring 217 to disengage the shoulder 216.

Thus disengaged the bar or member 211 will 1 remain stationary, and as the extra weight has been removed from the arm 200, the weight 203 will be sufficient to again raise the bars 190 and carry the mantle support back and through the opening 198 in the tract 51 and into position to be advanced by the carrier. All rotary movement of the bars 190 is prevented by the link connecting members 199, and at the same time the slots in one of said members will permit the parts to move slightly independently of each other to prevent straining of the parts if the necessity should so require.

The dipping tank 188 may be pro itled with a cover 224, which is adapted to be automatically removed and replaced in any suitable manner, but a simple and etlicient means for accomplishing this end com prises a rod or bar 225 journaled in suitable supports and extending across the frame adjacent the tank, and secured to which are arms 226, which are suitably connected to the cover 221', so that when the rod or bar 225 is rocked backward or forward the arms will withdraw or replace the cover. Pivoted to the standard 61 adjacent one of the arms 226 is a bell crank lever 227, one arm of which is preferably deflected so as to stand adjacent to one of the arms 226 and is pivotally connected thereto by means of an arm or extension 228. Pivotally connected to the other arm of the lever 227 is a dog or latch 22$), the pivot point of which is preferably located remote from the end of the arm, and adjacent said end is a laterally projecting pin or lug 230, which is adapted to be engaged by and support the free end of the latch or dog. This latch or dog is located in close proximity to the standard 61 and within the path of the upward movement of the lug or pin 11 1 on the piston 77, so that when the piston moves upward the latch or dog will be engaged and moved about its pivot by the pin or lug 11%, thus permitting the latter to pass, after which the latch or dog will fall into engagement with the projection 230 and in the path of the return movement of the pin 11-1t. As the piston descends the pin or lug 11 1 will enthe thus locked latch or dog 229 and rock the bell crank 227, which in turn will rock the bar or rod 225 and arms 226 and withdraw the cover. A. suitable weight 231 is arranged preferably on the rod or bar and so located as to continue the movement of the rod or bar 225 after it has been moved over the center. An adjustable arm 232 may be secured to the rod or bar 225 adjacent the opposite standard 61, which moves between two lugs or stops 233 on said standard to limit the movement of the arms 226 and the cover 224. In order to return the cover or close the tank there is provided an arm 23st which projects from the rod or bar 225, and pivotally connected to this arm is one end of a rod or bar 235, the other end of which passes loosely through a swiveled nut or bearing 236, supported by one of the arms 200, preferably adjacent the opposite side of the machine, and secured to the rod 235 is an adjustable sleeve or collar 237.

'When the arms 200 are moved downward during the opening of the tank, the bar or rod will. move through the nut or member 236, which latter turns about its pivot to permit such movement, but when the arms are released so that the weight 203 will return them to their normal position, the swiveled nut or member 236 will move into engagement with the sleeve or collar 23? on the rod and raise the same, thereby rocking the rod or bar 225, and will continue to move said bar 225 until the weight 231 thereon passes over the center, which latter will continue the movement of the bar 225 until the arm 232 engages its respective stop 233, at which time the cover 224 will be closed.

In order to prevent sparks from the burners from dropping into the dipping tank when the latter is open a shield 238 may be provided, which is supported preferably above the lower runs of the conveyer chain 48 by means of brackets or supports 239 on the tracks or supports 51.

From the above description it is thought that the operation will be fully understood, but briefly stated it is as follows: The mantles are first formed and secured to the supports 55 in any desired manner, preferably removably, after which the supports are placed upon the upper runs of the conveyer chains 48 between the projections 54, and preferably at the ends 57 of the guide boards 56, which latter serve as a means for assisting in properly placing the supports. The various regulating valves having pre viously been properly adjusted, the operatinghandle 96 is manipulated to operate the valve plug 91 to direct the air beneath the piston head inthe cylinder 79, to raise the same, the normal position of the piston head and rod being down. As the piston rises the rope or cable 74 will rotate the drum 60 to move the rod or bar 64 forward, the for- Ward extremity of which will press against one of the pins or projections 67 on the sprocket wheel 47, which will move the conveyer chains one step forward and thus intermittently advance the mantle supports The carrying or lifting reels rotate simultaneously with the conveyer-s, and as the supports reach the forward end of the conveyers one of the pivoted members 37 on one pair of the arms 36 of the reels 35 will on gage and cause the support to rest upon the seats 38 therein and carry the support to the extreme forward position and within the path of the upward movement of the brackets 167. This support will remain in this position during the reverse movement of the piston rod 77 and the rod or bar 64, and until the valve plug 91 is again operated to advance the conveyer. The operator then raises the handle 163 to cause the brackets 167 to raise the support from the members 37 of thecarrying or lifting reel 35. After disengaging the same the handle 163 may be lowered (or raised if the mantles are inverted), causing each of the mantles to pass over one of the burners 174, in which position they are retained by means of the counterbalancing spring 162. The valves 177, 184 may then be opened to supply fuel to the burners 174, which latter are lighted by means of the pilot burner 179. The mantles may be moved slowly up and down by means of; the handle 163, and the action of the strong flame will fill out and shape the mantles, after which the brackets 167 are raised and the support and the shaped manties are replaced upon the carrying or lifting reels 35, in the manner already set forth.

Before the mantles reach the carrying or lifting reels 35, the supports 55 are engaged by means of the links 124, which are raised from the upper runs of the conveyer chains by means of the lug 151 on the drum 60 engaging the arm 147 and moving the same about its pivotal support as the drum rotates forwardly to draw upon the rod or bar 149 .nd rock the shaft 122. This operation will raise the mantles upon the support so that they will stand between the two rows of burners 134. Simultaneously with the rais ing of the mantles between the burners, the

bar or rod 142 will operate the mixing valve 136 to furnish fuel to the burners 134. The mantles will remain between these burners until all of the cotton in the material has been thoroughly burned out and until the piston 77 descends to rotate the drum in the opposite direction, which will cause the screw or projection 150 to engage the arm 148 to move the bar 149 to rock the shaft 120 in the opposite direction, which will lower the links 124 to replace the support upon the upper runs of the conveyer chains, and also to lower the flame from the burners 134 in the .ianner already set forth. From this point the mantles are advanced to the shaping burners. After the mantles have been shaped the support is placed upon the tracks or guides 51 by means of the arms 36 of the lifting or carrying reels 35, and are advanced toward the rear of the machine and the dipping tank by means of the projections 54 on the lower runs of the conveyer chains.

The supports will then be interi'nittently advanced along this track or guide 51 until they reach the openings 198 therein, at which point the ends thereof will drop through the openings and upon the brackets 194, which are normally in close proximity to the openings. As the piston rises to rotate the drum 60 in a forward direction the pin or projection 114 thereon will move upwardly in the slot 212 and engage the top 220 thereof to raise the member or bar 211, causing the same to slide through the guide slot 210 on one of the arms 200 until the shoulder 216 thereon is forced by the spring 217 into engagement with one side of the arms 200. The piston then immediately descends, thus placing the weight of the bar or member 211 upon the arm 200 to overcome the weight 203. This will depress the forward end of the arms 203, and draw the rods or bars 190 with the brackets 194 and the support resting thereon dowmvard, until the mantles enter the dipping tank. As the pin 114 travels upward with the piston 77 it will engage and pass the latch or dog 229, which latter will fall into the path of the return movement of the pin after the pin has passed.

The downward movement of the piston will cause the pin 11a: to engage the locked dog 229 and iove the lever 22' aboutits pivot to rock the bar or rod 225 to throw the weight 231 over the center and draw upon the arms 226 to remove the cover of the tank. As the forward ends of the arms 2G0 move downward the projection 223 on the arms will engage the bar or member and shove the extremity against the tension of the spring 217 to disengage the shoulder 216. Thus re leased the weight 203 will raise the rods 190, brackets 19a and the support 55 thereon, so that the ends of the latter will pass through the openings 198 in the tracks or guides 51 and into position to be engaged by the projections 54;- on the conveyer chains and advance toward the rear of the machine. Upon the upward movement of the arms 200, the swiveled nut 236 thereon will engage the collar 237 on the bar or rod 235 to rock the bar or rod 235 to move the weight 231 to the other side of the center to close the tank. After being replaced, the supports are advanced toward the rear of the machine, where they are preferably lifted from the lower to the upper runs of the conveyer chains by lifting reels similar to those at the frontof the machine, and advanced to a point preferably in proximity to the point at waich they were originally placed upon the conveyer chains, at which point they are removed. The conveyer chains project for some distance beyond the dipping tank, in order that the mantles will have suflicient time in which to become thoroughly dry, before being removed from the machine. Thus it will be seen that with this improved machine the cotton is first burned out of the mantles, the mantles then shaped, after which they are dipped in a preserving solution, and finally allowed to dry before being removed from the machine. Furthermore, with this arrangement the valve 81 may be so regulated that the piston in the cylinder will move slowly at first and gradually increase in speed, which prevents the mantles from swinging upon or being thrown off of their supports, which would be the result if the piston and machine were started suddenly.

it is to be understood that the bar or rod 64 is of sufficient length to move the sprocket wheel 47' and advance the conveyer chains the full limit of movement before the stop or lug 151 engages the arm 1&7 to operate the rock shaft 120.
